Linux as 5.5 MySQL 5.0 数据库备份与恢复:
1, 用 mysqldump 命令进行备份:
在命令提示符窗口(注意不是 MySQL 的 MySQL Command Line Client 窗口)中输入,
mysqldump -hlocalhost -uroot -proot temp > temp_2011.sql
mysqldump -hlocalhost -u root -proot temp > temp_2011.sql
mysqldump -h localhost -u root -proot temp > temp_2011.sql
先进入到 MySQL想要存放备份文件的目录下(便于存放生成的*.sql文件).
也可以在命令里指定想要存放的目录:比如存放到根目录下,命令如下:
mysqldump -h localhost -u root -proot temp > temp_2011.sql > /2011.sql
其中-h,-u两个参数名与参数值之间可用或不用空格分隔,
但-p参数的参数名与参数值之间是一定不能加空格的,也可以这样输入:
mysqldump -hlocalhost -uroot -p temp > temp_2011.sql
Enter password: root
在后面再输入密码也可以成功.
-h指出备份的数据库在本机,-u指出用户名,-p指出密码,temp为数据库名,后面可具体指定备份的数据表.
结果生成的 temp_2011.sql 文件会自动存在指定目录下.
2, 用mysql 命令进行恢复:
mysql -hlocalhost -uroot -proot temp 输入此命令后,数据库中的数据将恢复到备份时的数据.
注意:恢复时, temp 必须存在,数据库可空.恢复时会自动删除要恢复的表,再重新创建,插入数据.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.
